LATHE ATTACHMENT FOR TURNING BEARINGS.

To all whom it may concern:

Be it known that I, CARL PHILIPP, citizen of the United States, residing at Jackson, in the county of Jackson and State of Michigan, have invented certain new and useful Improvements in Lathe Attachments for Turnmg Bearings, of which the following is a specification.

My invention relates to an improvement in lathe attachments for turning bearings, and the object is to provide means for turning off tumbling shaft bearings and cranks without cutting off the ridge rod arm of the tumbling or reverse shaft of locomotives.

A further object is that the attachment can be applied to any lathe, or, if desired, can be used independently of a lathe.

The invention consists of certain novel features of construction and combinations of parts which will be hereinafter described and pointed out in the claims.

In the accompanying drawings :Figure 1 is a view of the invention applied to a lathe; Fig. 2 is a view in side elevation of the attachment Fig. 3 is a sectional view through the pinions and gears and 4 is a detail.

A represents the bed of the lathe, and B is a tool post mounted thereon.

C is a bearing or head which is provided with a curved aw 1, the jaw having flanges 2 thereon. The shank 3 of the bearing received in the tool post B for supporting it in its operative position.

Gears 4, 4 are connected together by webbing 5, and are made in two sections, the gears having recesses 6, 6 formed in the webbing which are counterborcd to receive the flanges 2 of the bearing 0. The gears are connected together by the ordinary tap connection. The jaw 7 is connected to the jaw 1 by screw bolts 9 passing through the flanges 10 and 11 on the jaws 7 and 1, respectively, thereby holding the sectional gears upon the head C. The outer surface of the jaw 7 e tends outward beyond the gears 4, preventing anything from coming in contact with the gear teeth at the forward end of the at I tachinent.

A curved arm 12- is connected to the shank 3 of the bearing C, which is provided. with a forked end 13. Pinions 14, 14, are made integral with their sleeve and are mounted upon a shaft 15 in the forked end of the arm 12, the shaft 15 passing through the forked end of the arm. Pinions 14 are adapted to engage the gears 4, and the pinions being ro- Specifieation of Letters Patent.

tated through the shaft 15 thereby cause the gears 4 to rotate.

Located in suitable guide recesses in the sides of the gears are cutters or knives 17, they being adj ustably held in the recesses by screws 19, which extend through elongated slots 20 in the knives.

The shaft or piece of machinery to be operated upon'is passed through the central opening of the gears 4 and supported upon the lathe in the usual manner between cen ters. After this has been accomplished, power is transmitted to the shaft 15, which causes the pinions 14 to rotate and through their engagement with the gears 4 the gears are rotated and the shaft operated upon by the cutters or knives.

The attachment is capable of alongitudinal as well as horizontal adjustment, the shank 3 of the bearing being adjustable in the post B, and the post which is mounted u on the bed of the lathe, is capable of a longitudinal movement.

From the foregoing it will be seen that I have provided a very simple attachment which can be applied to any lathe for truing bearings of shafts, which attachment may be used independently of a lathe if desired. By this attachment the shafts can be properly centered and the bearings operated upon in any approved manner for truing them.

It is evident that more or less slight changes might be resorted to in the form and arrangement of the several parts described without departing from the spirit and scope of my invention, and hence I do not wish to be limited to the exact construction herein set forth, butz- Having fully described my invention, what I claim as new and desire to secure by Letters Patent is 1. In a lathe attachment for turning bearings, the combination with a head, of gear wheels having recesses therein for supporting the gears upon the head, means c0nnee-ting the gears together for retaining them in position on the head, cutters on the gears, and means for rotating the gears.

2. In a lathe attachment for turning bearings, the combination. with a head having flanges thereon, of gears made in sections, said gears having recesses therein in which the flanges of the head are received for sup porting the gears on the head, a Web connecting each section of the gears together for retaining them in position, a driving shaft having pinions thereon in engagement with on the flange of the first-named aw, a driv- 10 the gears for rotating the gears, and cutters ing shaft having pinions in engagement with on the gears. the gears, and cutters on the gears.
